LlNOLEUM-PRESS.

SPECIFICATION forming part of Letters Patent No. 699,753, dated May 13,1902. Application filed February 27,1902. Serial No. 95,969. (No model.)

To (LZZ whom it mag concern.-

Be it known that I, HENRY WILLIAMGOD- FREY, engineer, a subject of theKing of Great Britain, residing at Staines, in the county of Middlesex,England, have invented a certain new and useful Linoleum-Press, of whichthe following is a specification.

According to this invention the linoleum or the like passes around aheated rotating drum, against the surface of which it is pressed by twohydraulic-pressure plates. These plates are connected together and intheir normal positions are the one vertically above and the othervertically beneath the axis of the drum; but when water is admitted tothem they press the linoleum against the drum and are carried aroundwith it through a smallangle. At the end of their travel the supply ofwater is automatically cut OE and the water allowed to escape from thepresses. The lower plate is suitably weighted, so that the plates nowswing back to their normal position, on reaching which the valves areagain operated auto matically to admit water. The plates take hold of anew piece of linoleum and are again carried around by the drum. Theplates are thus kept continually oscillating, their dimensions andtravel being of course so related that no parts of the linoleum shall bemissed.

Figures 1 and 2 are front and side elevations of the apparatus Figs. 3and 4 are vertical sections on the lines 3 3 and 4 4L, and Figs. 5 and 6are front and side views of the valve mechanism.

a is the framing,carrying in bearings a the trunnions b of the drum 6,constantly rotated through the toothed wheel 12 The drum is bored out,as seen in Figs. 3 and 4:, so that steam may be supplied to it forheating it. At each end of the drum is a frame 0, loosely surroundingthe trunnion b, so that it can oscillate upon it. The frames areconnected together top and bottom by tie-rods c and carry twopressure-plates (Z d, operated by four hydraulic presses (P. The lowerplate d is made heavier than the upper, so that when the plates ceasetheir grip of the drum the frame 0 swings back to the position shown inFigs. 1 and 2. Pivoted at (Z d to the plate d are links cl", connectedto rocking levers d turning on pins d on the frame 0 and carryingrollers d bearing against the plate d, so that when the water escapesfrom the presses the fall of the plate d lifts the plate (1. The plates(1 cl are concave toward the drum and may, if desired, be fitted with acoil of pipes (Z as seen in Fig. 3, for cooling purposes.

I will now describe a mechanism for operating the valves which I havefound to work well 3 but I do not limit myself to this arrangement.

e is the main inlet-pipe leading to the valve 6. f is the exhaust-pipeleading from the valve f. The valves 6' f communicate with the system ofpipes g, leading to the four presses diand are operated byscrew-threaded stems c f passing through nuts c f on the valve-casingand carrying the pinions at meshing with one another. The pinions haveon them studs c f. All these parts are carried by a plate 0 on one ofthe oscillating frames 0.

On one of the bearings a is a plate (1 having pivoted to it two arms hh, connected by a spring 7L2, the arm it being suitably cranked, so asnot to foul the stud e h 71 7&5 h are fixed stops on the plate a 71represents the linoleum, which travels in the direction of the arrow inFig. 1 over the guide-roller i, around the drum, and under the rollerThe parts are shown at the moment when the valve 6 is just about toopen. When it has opened, as described below, pressure is admitted tothe pipes g, the rams press the plates onto the linoleum around the drum,and the frame and plates swing down to the position shown in dots inFig. 3. Before this positionis reached, however, the stud f comesagainst the arm h and moves it up, extending the spring 71 which is not,however, strong enough to move the pinions until they are started by thearm h coming against the stop 71 but as soon as they are started thespring gives them a good swing around, (owing to the arm h being againstthe stop k lifting the valve f well ofi its seat and closing the valve ehard down. The plate (1 now falls and lifts the plate d, and the frameswings back toward the vertical, so bringing the stud c against the armh and pulling the arms 71 h down onto the stops 71 it, so that thepinions are again swung around, opening the valve 6 and closing f. Theextreme positions of the 5 pins 6 are shown at e f.

What I claim is- 1. The combination of a continuously-rotating drum, aframe oscillating upon it, a plate carried by the frame, and means forpressing the plate intermittently against the drum.

2. The combination of a continuously-rotating drum, a frame oscillatingupon it, plates carried by the frame, means for pressing the platesintermittently against the drum, and apparatus connecting the plates sothat they move in and out together.

3. The combination of a continuously-rotating drum, a frame oscillatingupon it, plates carried by the frame, means for pressing the platesintermittently against the drum, a rocking lever pivoted on the frameand bearing against one plate, and a link connecting the lever to theother plate.

4. The combination of a continuously-rotating drum, a frame oscillatingupon it, plates carried by the frame, hydraulic presses on the frameacting on the plates, and means for intermittently admitting water tothe presses.

5. The combination of a continuously-rotating drum, a frame oscillatingupon it, plates carried by the frame, hydraulic presses on the frameacting on the plates, a valve for 35 the presses, and means forautomatically opcrating the valve by the movements of the frame.

6. The combination of a continuously-rotating drum, a frame oscillatingupon it, plates carried by the frame, hydraulic presses on the frameacting on the plates, a valve for the presses carried by the oscillatingframe, and means carried by the stationary framing for operating thevalves.

7. The combination of an oscillating press, a valve moving with thepress, a valve-stem operating the valve, a disk on the stem, a stud onthe disk, and a spring-arm turning on a stationary pivot and adapted toengage the stud.

8. The combination of an oscillating press, an inlet and an exhaustvalve moving with the press, valve-stems operating the valves, pinionson the stems meshing with one another, studs on the pinions, and aspring-arm turning on a stationary pivot and adapted to engage the.studs.

9. The combination of an oscillating press, an inlet and an exhaustvalve moving with the press, valve-stems operating the valves, pinionson the stems meshing With one another, studs on the pinions, a pair ofarms turning on stationary pivots, a spring connecting the arms, andstationary stops for the arms.
